ZCS Version

This article contains information for recreating a certificate using the command line interface in both ZCS 4.5.x and 5.0.x. In deployments of 5.0.x and later, this process does not need to be done via the CLI. Using the Administration Console Certificates Tools will simplify this process, and generally eliminates any issues or errors encountered by using the CLI. If you choose to recreate your SSL certificate manually instead of using the Administration Console Certificate Tools, please read all instructions with particular attention to version specific sections and notes before attempting to recreate a self-signed SSL certificate.

Why Recreate My Certificates?

Your certificates are expired and need to be recreated if you see an error like this when you run zmprov.

If you want the common name show up in the CA rather than 'Zimbra Collaboration Suite' because you have several zimbra servers. Please Note: I probably have unnecessary steps in this section here, but this is what I did to get it working for me.
